Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lamps. Background Art
[0002] During operation, lamps generate high heat, which needs to be dissipated in time to ensure normal operation and extend the service life of the lamps. Existing lamps generally install the light source and driver in one piece inside the lamp housing, and the housing is used for heat dissipation. However, the light source and driver each generate a lot of heat during operation, and the heat dissipation effect is poor if the housing is used for heat dissipation alone.
[0003] Then, for example, the lamp disclosed in Chinese patent authorization announcement number CN103672482B, by placing the driver on the split shell, the heat dissipation of the lamp alone is better than when the driver and the lamp shell are fixed together. However, in this solution, the driver is simply accommodated in the split shell, and the light source is also simply fixed on the lamp shell, and the actual heat dissipation effect needs to be improved. Utility Model Content

[0033] like Figures 1 to 6 As shown, a lamp structure of the utility model includes a light source 1, a lens 2, a heat dissipation body 3, a driver 4, a heat dissipation back cover 5 and a track head 6.
[0034] like Figures 2 to 4 The heat dissipation body 3 may be a rectangular body, and the bottom is concave with an installation cavity 31 with an opening at the bottom, the top surface of the installation cavity 31 is provided with a lamp source heat dissipation plane 311, the lamp source 1 is located in the installation cavity 31, and the front surface 11 of the lamp source is a light-emitting surface, and the back surface 12 of the lamp source is coated with heat dissipation paste (not shown) and is closely attached to the lamp source heat dissipation plane 311; by filling the heat dissipation paste between the back surface 12 of the lamp source and the heat dissipation plane 311 of the lamp source, a good heat conduction effect is achieved, the heat conduction speed is accelerated, and the heat dissipation efficiency is improved.
[0035] See also Figure 5, and the heat dissipation rear cover 5 is locked on the top of the heat dissipation body 3 and a rear cover chamber 51 is formed between the two. The top surface of the rear cover chamber 51 away from the heat dissipation body 3 is a driver heat dissipation plane 511. The driver 4 is locked in the rear cover chamber 51, and the top surface of the driver 4 is closely attached to the driver heat dissipation plane 511. Thus, the driver 4 and the light source 1 are separated and located in different chambers, and the light source 1 is closely attached to the heat dissipation body 3 for efficient heat dissipation, and the light source 1 is also closely attached to the heat dissipation rear cover 5 for efficient heat dissipation, so as to increase the heat dissipation area of the entire lamp structure. At the same time, the heat dissipation surface of the back side 12 of the light source is far away from the heat dissipation surface of the back side of the driver 4, so as to improve the overall heat dissipation effect.
[0036] The driver 4 is closely attached to the driver heat dissipation plane 511 and is spaced from the top of the heat dissipation body 3. The driver 4 is spaced from the heat dissipation body 3 of the light source 1, and the driver 4 is cooled separately.

The heat dissipation back cover 5 is locked to each connecting column 321 by screws 7, which can reduce the contact area between the heat dissipation back cover 5 and the heat dissipation body 3, reduce the heat conduction of the heat dissipation back cover 5 on the heat dissipation body 3, and enable the lamp source 1 and the driver 4 to fully realize split heat dissipation.
[0037] The light source 1 may be two or more SMD light source boards. In this embodiment, three SMD light source boards are provided and are arranged side by side and closely attached to the light source heat dissipation plane 311 of the installation chamber 31 .

[0039] The area of the light source heat dissipation plane 311 is not less than half of the area of the light source back 12 and is tightly matched with the middle of the light source back 12 through screws 7 to ensure sufficient contact area. At the same time, in this embodiment, the top surface of the installation chamber 31 on the inner side of the bottom of the heat dissipation body 3 is provided with a plurality of heat dissipation grooves 312 on both sides of the light source heat dissipation plane 311; the outer surface 34 of the heat dissipation body 3 is a plane. The heat dissipation grooves 312 can be provided to increase the heat dissipation area and improve the heat dissipation effect, and the outer surface 34 of the heat dissipation body 3 is provided as a plane so that the outer surface is flat and easy to clean.
[0040] The heat dissipation groove 312 and the rear cover installation area 32 are recessed on the heat dissipation body 3, so as to reduce the weight of the heat dissipation body 3, save materials and reduce costs.
[0041] The lens 2 is installed in the installation chamber 31 and is located below the front face 11 of the light source. It is used to cover the light-emitting surface of the light source 1 to focus light and protect the light source 1. In this embodiment, the lens 2 and the light source 1 are both locked and installed in the installation chamber 31. This can facilitate subsequent maintenance, and setting more than two lenses 2 can prevent the light source 1 from being damaged at the same time, and can also facilitate subsequent maintenance and replacement.
[0042] A rotating shaft hole 52 is provided on one side of the driving and cooling plane 511 of the heat dissipation rear cover 5; the rail head 6 has a rotating shaft 61 which is rotatably installed in the rotating shaft hole 52. The lamp structure of the utility model can be installed on a rail (not shown) by means of the rail head 6, and the heat dissipation body 3 can be rotated and adjusted relative to the rail head 6.
[0043] In summary, a lamp structure of the utility model is provided with a separate and independent installation chamber 31 and a back cover chamber 51, and the light source 1 and the driver 4 are respectively attached to the light source heat dissipation plane 311 of the installation chamber 31 and the driver heat dissipation plane 511 of the back cover chamber 51, thereby enhancing the heat dissipation efficiency, improving the heat dissipation effect, and prolonging the service life of the lamp.
[0044] The driver 4 and the light source 1 are installed independently, which is also convenient for subsequent upgrade and maintenance of separate accessories.
[0045] The above is only a preferred embodiment of the utility model, and the protection scope of the utility model is not limited to the above embodiments.
